All puzzle boxes from Klobucher are composed of small cube units.
The boxes have the shape of a cuboid, whereby the most of them are 3x3 or 4x4 cubes.
As exotic timber is used for the small cube units,
the appearance of the boxes is like patchwork.
At the front and the back of the boxes is either a circle shaped ornament
or a point shaped ornament in the shape of Little Bear/Little Dipper and Great Bear/Big Dipper.

Inside the boxes are pins.

All of his boxes are maze boxes and are built with the same mechanical principle.
The number of moves to open the boxes can be very high,
for example MMMDXLVI needs 3546 moves to open.

Long move sequences, which appear often, alternate again and again with move sequences,
which appear only once. Therefore, it is extremely difficult to open the boxes.

All his puzzle boxes are accompagnied by a small solution sheet.

Robert Yarger with his wife
holding in his hand a container that holds a queen bee.

Robert Yarger is besides Kagen Schaefer one of the most important
and famous American artists for sequential movement boxes.
Many of his boxes are three-dimensional mazes or sliding puzzles.

His most famous boxes are the Stickman No.3 Puzzle Box and the Stickman No.5 Puzzle Box.

It is striking about Yarger´s boxes that the function mechanism of his boxes
is immediately recognisable. That is because the opening mechanism is not hidden inside the box,
but clearly visible from outside. As the mechanism constitutes the major part of the box,
many of his sequential movement boxes are not perceived as boxes,
but rather as a puzzle or game.

Almost all boxes are without a relationship to a topic.
Only few of the boxes, such as the Grandfather clock puzzlebox
and the Lighthouse Puzzlebox are depictions of images.

Yarger uses exotic timber for the production of his boxes.

All boxes are numbered consecutively and have additionally a second name.
Only 3 to 4 boxes are produces per year in a limited edition,
thereby every box is delivered with an instruction booklet.
Unfortunately the boxes are faster sold than produced.
